Gasoline for Turbo engine

[The Gadget Shop]

You can bluff and bluster all you like but that's the truth.

Fine, but you haven't shown us that you are any more enlightened. I am aware
of different regional models being tuned/setup differently to match
regulations and available fuel. So if you have anything other than hot air
to contribute, please do - we all prefer to intake cold air...

OK, here's what I see.

a) Someone who has a lighthearted comment that the fuel sold in
Australia is better, honestly believing so before being corrected.

b) Same someone being corrected, but doesn't seem to let up that
said fuel sold in the United States is equivalent to that sold in
the United States.

As for the octane requirements of gasoline engines and the fuel
needed to supply those requirements......

Believing that 96 [RON] octane premium unleaded fuel sold in
Australia has greater anti-knock resistance than 91 [(R+M)/2]
octane premium unleaded fuel sold in the United States is like
saying that 100 km/hr is faster than 62.5 mi/hr. You're dealing
with **different measurement scales**. While there are differences
in anti-smog, sulfur, etc requirements, the anti-knock properties
should be the same.

Regular: 91 RON should be equivalent to 87 (R+M)/2.
Premium: 96 RON should be equivalent to 91 (R+M)/2.

If you can't understand this, then I suppose there is nothing
more that can be done to help explain it to you.

Correction. Should have read:

Octane booster is a joke. Period. Toluene/Xylene are about the only
products I would ever recommend to increase octane rating. The guy was
worried about the cost of fuel, not the availability, you do realize that
"octane boosters" only raise the octane (at most) .5 to .7 octane (thats
what they mean by 5 to 7 points increase..".5"=5 points, ".7"=7points)
....it will take an awful lot of bottles to increase 87 octane to 91 or
greater.

.... why aren't these guys being sued by expensive car owners whose engines
are being fried because the octane booster didn't actually deliver on its
claims of 15 points? Let's see.. 91 + 1.5 = 92.5. And who says I use only
one bottle?

Well - I think there are some products (like xylene) that provide a
blended octane increase. They have an inherently higher anti knock
rating and using enough roughly brings the octane rating up in
proportion to the amount used. Xylene has a (R+M)/2 octane rating
of 117.

Then there are anti-knock additives - I think tetraethyl lead would
be the best known. They improve the anti knock properties of any
fuel, but don't have any "octane rating" per se because they can't
be used as a fuel.

Except that they are not safe for catalytic converters. I use an octane
booster. I can get 92 octane (AKI) and I use it to get close to the 93
octane that the car needs. It does help with knock on hot days. However,
one has to be careful since the really effective boosters have lead in them
and will destroy the catalytic coverters; an expensive fix.

Never said otherwise. Lead is illegal except for off-road purposes.
The lead additives I see in auto parts stores clearly state that
they are meant for private roads/marine/track/aviation use.

However - I was just getting that toluene/xylene simply blend into
a roughly average octane rating. Lead actually improved the anti
knock resistance regardless of the base fuel.
